Some guy on Gasbuddy said Diesel was $2.99, 2 hours before I got there, some how I think he was lying.

With all the changes GasBuddy has gone through over the last few years, I've noticed a precipitous drop in mid/premium/diesel price accuracy, and an overall downturn in price updates. It got a lot worse once they ditched the forums and whiteboards. I think it drove off a lot of old-timers who still used the website for posting prices.

If you go back up a few posts and read about the BP in my area that's $2.799, I too thought it was a bogus report for a long time until I pulled in to verify it myself. But it was real. So every now and then they do still find me a bargain. But not nearly often enough.

GasBuddy helped me find some stations that still charged only $2.919 for diesel when almost all the others were $3.29-$3.34. I got four fills from one of those stations before they raised their prices -- except I just noticed that the least convenient of them is still $2.919. So maybe when I need to refuel and I'm in the area.....

This afternoon I noticed a station charging $3.09 while driving past on the freeway. GB showed a price of $3.29, so I updated the price. Thirty minutes later I stopped on the way back to fill up, taking advantage of a 3-cent discount so only $3.06 for me, and at least two of the other diesel pumps were in use. All the other stations in the area were still $3.29, and the ones close to my home are $3.25.

I've been driving more lately; I've filled up ten times in the last 31 days, and I was driving my other car over the Memorial Day weekend so really ten times in 28 days. And averaging 45.5 mpg which is the best fuel mileage I've ever obtained in almost 15 years of ownership.

Okie still frequents here? Guess I haven't missed much in my absence (no problems with any of the 5 TDIs here).

Filled up today at HEB (regional supermarket monopoly in Central Texas) for $2.79. Filled up mom's mk7 at Shell for $2.99.

Filled up in CA two weeks ago at a Food 4 Less in Perris, CA for $3.83.

For everything other than both trucks (GMC K3500 6.5L and Ford F-Super Duty 7.3L, both 1995), I have a 90 gallon transfer tank here at the ranch, obtained when diesel was $2.69/ga (about a month and a half ago), also filled up with Optilube XPD.

GasBuddy is a useful tool although as others have noted since they revamped their website it is more of a pain to use. I find I need to switch it to RUG then back to diesel everytime I scroll the screen in order to get the most current reported price. For the most part that I've seen firsthand reported diesel prices are spot on in my area.

As I take annual road trips to the same areas I've noticed the stations with the cheapest diesel on GasBuddy remain so year in and year out. Once I know where these stations are (I keep a list of them for easy reference) I don't need to scope out all stations along the route for lowest price. Some states are a better deal than others too - I find Ohio is almost always lower than Pennsylvania (fuel tax comes into play here) for example.

I think some people don't really pay attention to where they are posting which prices. Especially when it a fuel they aren't purchasing. I've noticed one of the new QTs by me always has prices for everything but rug listed incorrectly.

Fuel Economy: ALH wagon getting over 40 in the city, 17mpg in the 4x4, Not enough miles yet on the 2015 GSW

About to cross Kansas again. I am seeing $2.96 average (recent reports) early in the drive, and $2.99 and higher later out West ($3.15 if you don't look ahead and plan!), but hoping to find $2.89 at known better locations. I will know by tomorrow ~8am after ~200 miles. Seeing is believing.
